United States Patent "ice BED CONSTRUCTION Robert B. Murchie, Traverse City, Mich. Application February 29, 1956, Serial No. 568,465 7 Claims. (Cl. 317) This invention relates to bed constructions generally and more particularly to roll-away type bed constructions.

Prior roll-away beds generally have been of the folding type and attendant therewith are numerous disadvantages, among which are the ever present likelihood of upsetting when in the unfolded position and the usual requisite that the mattress therefor be of a type which folds within the frame, whereby the comfort characteristic of conventional beds employing box springs, for example, has not been heretofore obtainable with known types of roll-away beds.

An important object of the invention is to provide an improved bed construction capable of supporting conventional springs and mattresses having novel means whereby the complete assembly may be placed in a sidewise position and conveniently wheeled from place to place so that it is particularly adapted for use in hotels where the floor space is intended to be used for other purposes as well as sleeping rooms. Other important objects of the invention are to provide auxiliary means adapted to be secured to the main frame of a wide variety of conventional bed constructions and constructed with respect thereto for supporting and rolling the entire weight of the main frame, springs and mattress when the assembly is placed in a sidewise position; to provide such auxiliary means in the form of an undercarriage including a rolling carrier adapted and intended to be mounted in a concealed position beneath the main frame of a bed construction, the said undercarriage comprising a rolling carrier and having track means to slidably support the rolling carrier whereby it may be laterally extended from the said concealed position and pivoted with respect to the main frame so as to be disposed and secured in an operative position to enable the maneuvering of the entire assembly through narrow corridors; to provide an undercarriage for a bed construction which is simple and economical of construction, which, when combined-with the latter, is safe and convenient to operate and which combination subserves varied and extensive conveniences.

The above and other objects of the invention will be apparent during the course of the following description, reference being bad to the accompanying drawings, wherein preferred embodiments of the present invention are clearly shown.

Generally, the invention comprises novel auxiliary means intended and adapted to be readily attached to conventional bed frames, to be neatly supported by and beneath the same and to be laterally extended therefrom for conveniently and safely transporting the main frame, springs and mattress from place to place when the assembly is tilted to a sidewise position. The invention also comprises the combination of the auxiliary means and a bed frame, preferably a rigid frame, constructed and arranged to form an improved roll-away bed construction providing the advantages of portability without detracting in any way from the comfort provided by conventional beds. The invention will be described first with respect to one form of the invention embodied in one construction of auxiliary means shown as an integral part of a bed construction, and second with respect to another form embodied in a modified construction of auxiliary means shown removably secured to a conventional bed frame for converting the same to a roll-away type bed construction.

In the embodiment of the invention shown in Figs. 1-4, the bed construction generally comprises a floor supported rigid bed frame 7 adapted and intended to support conventional springs and mattresses, a box-type spring 8 and conventional mattress 10 being shown. Shown permanently associated with the bed frame is one construction of auxiliary means comprising an extensible rolling carrier, generally designated 11, slidably supported in a concealed position beneath the bed frame. On the free end of the rolling carrier 11 are a pair of spaced straps 13 which cooperate with another pair of similarly spaced straps 15 secured to the opposite side of the bed frame from which the rolling carrier 11 extends. The rolling carrier 11 is adapted to be laterally extended from its concealed position to a position beyond the bed frame and be moved so as to be perpendicularly disposed with respect thereto, in which position the cooperating straps may be drawn taut over the spring, mattress and bedding, the assembly lifted and placed in a sidewise position for wheeling the same from place to place.

Referring to the structure in more detail, the bed frame 7 is rigid and comprises longitudinal or side bars 17 secured to transverse or end bars 19. The side bars 17, as shown, are conveniently in the form of angle irons disposed so as to have an angle or web upright to prevent lateral movement of the spring relative to the main frame. At the four corners, inside of the bed frame 7, are horizontal plates 21 to which are secured suitable casters 23 for wheeling the bed assembly when it is in the horizontal position. As part of the construction of the auxiliary means and secured at each of its ends to the end bars 19 within the bed frame 7 is a longitudinal central bar 25 which may be conveniently formed of two angle irons with their angles or webs placed back to back for supporting track means. The track means is provided within the bed frame 7 for slidably supporting the rolling carrier 11. The track means in the form shown-comprises rectangular tracks generally designated 9, defined by pairs of parallel transverse members 27, one such pair being shown in detail in Fig. 5. Each transverse member 27 comprises rigid horizontal bars 29, 31. suitably spaced so as to form open slideways. Each pair of transverse members 27 is disposed so as to have the slideways in face to face relation so as to define the rectangular tracks 9. Each transverse member 27 is secured below a horizontal web on the central bar 25 and the horizontal web on one of the side bars 17 of the bed frame 7. Affixed to the same side bar on the bed frame 7 in front of each of the tracks 9 are upright guard plates 35 for protecting the springs 8 and for bracing the rolling carrier 11 when in its operative position. The guard plates 35 prevent further movement of the rolling carrier 11 toward the upper surface of the bed frame 7 so that the springs and mattress and the rolling carrier are rigidly secured relative to the main frame when the straps are drawn taut.

The rolling carrier 11 is made up of pairs of flat plates which slide within the tracks 9 on the bed frame 7. Each pair of plates consists of a platform plate 37 which is adapted to extend beyond the body of the bed frame 7 and a retainer plate 39 which is suitably hinged, as at 38, to the platform plate 37 and which remains within the tracks 9 of the main frame 7 in a manner to be presently described. The platform plates 37 have affixed thereto suitable caster units for conveniently wheeling the assembly when in a sidewise position. The central pair of plates is wider than the end pairs on each side thereof for the purpose of affixing a pair of rigid caster units 41 to the central platform plate. Swivel caster units 43 are secured to each of the end platform plates. Secured to all of the platform plates 37 by suitable spacers 40 so that they will move as a unit are a pair of longitudinal bars 45, 47.

The platform plates 37 and the retainer plates 39 slide within the tracks 9 and are supported therein at their edges by the open ended slideways formed in each pair of transverse members 27. When the rolling carrier 11 is laterally extended from the bed frame 7, it remains aflixed to the frame by virtue of the construction of the retainer plates 39 and suitable stops within the tracks 9. Fig. 4 shows one of the transverse members trate the detail of the construction of the retainer plates 39. It will be noted that the retainer plates 39 are wider than each of the platform plates 37 to which they are hinged so that their edges slide deeper within the open slideways between the horizontal bars 29, 31 and engage stops 33 (Fig. 5) between the horizontal bars 29, 31. The stops 33 are disposed at the ends of the tracks 9 from which the rolling carrier extends and are spaced so as to prevent the retainer plates 39 from being withdrawn from the bed frame 7. The rolling carrier 11 in its concealed position beneath the bed frame 7 is supported solely by the tracks 9 so that it does not rest on the floor. In the instance shown, the casters on the rolling carrier 11 are smaller than the casters on the bed frame 7, but it will be understood that the frame 7 can be formed with short legs so as to raise the same slightly in the event it becomes desirable to provide the rolling carrier with larger casters than that on the bed frame. It will be apparent also that the end bars of the bed frame may be formed so as to telescope to accommodate springs and mattresses of varied widths. lengths can be accommodated by the bed construction shown, but if desired, the side bars may also be constructed to telescope in which case the central bar 25 would also be constructed to telescope at one of the ends 27 broken to illus- Springs and mattresses of different thereof beyond the track means. It will also be apparent that if found to be desirable the casters on the bed frame may be suitably hinged by means (not shown) wherewith the said casters may be swung away from the bed frame and against the springs and mattress. This is advantageous when the bed construction is placed in the sidewise position for rolling the same in that nothing protrudes from the body of the bed and a minimum of transverse width of the assembly is thereby presented. While the form of auxiliary means of the embodiment is shown as an integral part of the bed construction, it should be understood that, if desired, the auxiliary means can be manufactured and supplied as a separate subassembly adapted for attachment to a conventional bed frame.

When the bed is made up for sleeping purposes, the rolling carrier is slid within the tracks into its concealed position beneath the bed frame, and the pairs of straps 13 and 15 are likewise placed beneath the bed frame so that no obstructions are presented beyond the bed assembly. When it is desired to transport the assembly from the room, the rolling carrier is laterally extended from the bed frame and raised to a perpendicular position and the cooperating pairs of straps are secured together and drawn taut over the spring, mattress and loose bedding. The entire assembly is then tilted and placed in a sidewise position so that the casters on the rolling carrier engage the fioor and the assembly is conveniently wheeled from the room. Throughout the specification and in the appended claims when the term bed assembly or assembly is used, it is intended to mean the bed frame, the auxiliary means including the rolling carrier, the spring and mattress, and whatever loose bedding, linen, etc., that may be associated therewith. Because the assembly is transported in a sidewise position, it can be easily maneuvered through narrow hallways and the length of the rolling carrier being nearly as long as the bed frame together with the secure manner of affixing the bed frame, spring and mattress to the rolling carrier insures safe handling of the assembly.

Referring now to Figs. 6l0, therein is shown a preferred form of construction of the auxiliary means embodying the invention. The auxiliary means in this embodiment is in the form of an undercarriage, generally designated 51, which includes a rolling carrier, generally designated 53; the auxiliary means being shown removably secured to one type of standard bed frame. The undercarriage is adapted to be readily attached to the bed frame by way of clamps on the end bars of the frame and by pivot-supports on one of the side bars of the frame, as will be described. The bed frame is entirely conventional in construction and consists of a pair of end bars, generally designated 55, which are constructed to telescope so as to provide the bed frame with adjustably different widths to accommodate springs and mattresses of varied size. The telescoping feature of each of the end bars is accomplished by a pair of superpo sitioned angle irons 55a and 551) which are slidable relative to each other and are adapted to be secured in settable positions by suitable means, as for example, by a clamp 57. Fig. 10 is a detailed view of the telescoping arrangement of one of the end bars wherein the clamp 57 has a body portion 57a of angular construction and which conforms to the shape of the angle irons 55a,

55b and has inturned contiguously disposed ends 57b, I 570 which have aligned apertures for receiving the thumb screw 59, the shank of which bears against the underneath angle iron 55b and prevents relative movement between the latter and the angle iron 55:: when tightened. Removably secured to the ends of each of the end bars 55 is a front side bar 59 and secured to the opposite ends of each of the end bars 55 is a rear side bar 61. For convenience of description, the side of the bed frame from which the rolling carrier extends will be referred to as the front side and the side opposite thereto as the rear side. At each of the four corners of the bed frame is an upright leg 63 of limited height, one end of which is supported by a suitable caster unit 65, the other end of which is bent over as at 67 and removably secured to both the end bar and the side bar. The short legs support the bed frame a sufiicient height from the floor to permit the caster units on the rolling carrier to be of larger size to facilitate rolling of the assembly when it is placed in a sidewise position.

The undercarriage 51 comprises a longitudinal central bar 69, the ends of which are adapted to be secured to the end-bars of the main frame. The central bar 69 may be secured to the main frame in any of well-known means and in the instance shown the central bar is secured at opposite ends to each of the clamps 57 which are a part of the bed frame of the type shown, it being understood that clamps of any suitable type can be made a part of the construction of the undercarriage if so desired. The undercarriage also comprises pivot-supports which are adapted for simple attachment to the front side bar 59 of the bed frame. A central pivot-support, generally designated 71, is secured substantially centrally of the front side bar 59 and a pair of end pivot-supports, generally designated 73, are secured to the front side bar adjacent the ends thereof within the bed frame. Each of the pivotsupports consists of a short length of angle plate, one web of which is secured to the underside of the front side bar 59, the other web of which depends therefrom and is specially formed in identical manner for the end pivotsupports 73 and in somewhat similar manner for the central pivot-support 71. The depending portion for the central pivot-support 71 is cut-away in its central portion and suitably bent to form a pair of spaced hook members which are best shown in Fig. 9 and designated 71a. The depending portion for each of the end pivot-supports 73 is likewise cut-away in its central portion and suitably bent to form a lug and spaced therefrom a hook member, the latter being disposed closest to the central pivot-support 71. The details of the construction of one of the end pivot-supports 73 is likewise shown in Fig. 9, the hook member of which is designated 73a and the lug 73b. The pivot-supports serve a number of functions which include, among others, that of providing a pivot axis about which the rear side of the rolling carrier is pivoted, bracing and preventing further movement of the carrier toward the bed frame when in its operative position, and acting as a support to retain the front side of the rolling carrier off the floor when in its concealed position beneath the bed frame, all in a manner as will be more particularly described. It will be noted that optionally and preferably there is provided a transverse brace plate 68 secured at one end to the central bar 69 and at the other end to the front side bar 59 by way of the central pivot-support 71. Each of the end pivot-supports 73 by means of its lug 73b support one end of the track means generally designated 75. The track means consists of a pair of spaced transverse rods 77 each of which is secured at one end to the central bar 69 and at the other end to the lug 73b on one of the end pivot-supports 73. Each of the rods 77 is slightly inclined from the hori zontal, being higher at the end which is secured to the central bar 69 so that, in movement of the rolling carrier into its concealed position beneath the bed frame, the rear side thereof is slightly raised so as to be on a level approximately with the plane of the bed frame. The hook members of the pivot-supports do not depend from the under side of the front side bar 59 to the extent of that of the lugs where the transverse rods 77 are secured, so that when the rolling carrier is engaged in the hook members in its concealed position, the front side bar thereof is on substantially the same level as the rear side bar. Each of the rods 77 has concentrically disposed thereabout resilient means 79 which are adapted to bias the rear side of the rolling carrier toward the pivot sup: ports 71, 73 to prevent accidental displacement laterally of the rolling carrier when in its concealed supported 3 position. If desired, the hook members on the pivot-sup ports can be' arranged with respect to the rolling carrier to engage and support the same without the need of the resilient means 79.

The rolling carrier 53 has a frame which is generally of tubular construction and comprises a longitudinally extending front or forward tubular member 81 and a longitudinally extending inner tubular member 83 which are secured together by a central and a pair of end transverse tubular members 85. The connection of each of the transverse tubular members 85 to the forward tubular member 81 is different than the connection with the inner tubular member 83. The connection between the transverse tubular members and the inner tubular member 83 is of special construction to permit of pivotal movement of the rolling carrier to a perpendicular position with respect to the bed frame while retaining the inner tubular member 83 within the confines of the bed frame; that is to say, in the pivotal movement of the rolling carrier to operative position the inner tubular member 83 does not extend beyond the vertical web of the front bar 59. To accomplish this, the transverse tubular members 85 are connected to the underside of the inner tubular member 83. More specifically, at the area of connection the uppermost points on the circumferential surface of each of the transverse members 85 are tangent the lowermost points on the circumference of the inner tubular member 83. Figure 9 best shows the detail of the connection between one of the end transverse tubular members 85 and the inner tubular member 83. Even greater detail of this connection is shown in the sectional view of Figure 11 for the connection between the central transverse member 85 and the inner tubular member 83. By thus securing the transverse tubular members to the underside of the inner tubular member, the rolling carrier may be pivoted to a perpendicular position while retaining the inner tubular member within the confines of the bed frame. A platform plate 87 is secured on the inside of each of the ends of the tubular framework for the rolling carrier and extends the length of each of the transverse tubular members 85 beneath which it is secured by welding or in other known manner. A swivel caster unit 88 of standard construction is secured centrally of and to the under side of each of the end platform plates 87. Similarly, a central platform plate 89 is secured to the under side of the central tubular member and carries on its under side a pair of rigid caster units 9.1: disposed for rolling the carrier in the direction of its longitudinal axis. The connection between the central platform plate and the central tubular member is preferably braced at one end as at 90 in Figure 11. Rigidity is provided for the frame of the rolling carrier by a pair of longitudinal braces 93 which are secured to and extend between the central platform plate 89 and one of the end platform plates 87 and by a similar pair of braces 95 which are likewise secured to and extend between the central platform plate 89 and the other of the end platform plates 87.

As in the previously described embodiment, the rolling carrier is retained in its operative position perpendicularly with respect to the bed frame with the aid of the springs and mattress by securing means in the form of pairs of spaced straps, one pair of straps being spaced and secured to the free end of the rolling carrier and the other pair being similarly spaced and secured to the bed frame. The two connectors on the free end of the rolling carrier to which one pair of straps is secured are shown in Fig. 6 and designated 97, while the two connectors on the bed frame to which the other pair of straps is secured are shown in Fig. 8 and designated 99.

In assembling the auxiliary means of the form shown in Figs. 6-11 to a conventional bed frame, the task is simplified in that only holes need be drilled in the horizontal web of the front bar 59 of the bed frame for attaching the central and end pivot-supports 71, 73 respectively. The central bar 69 of the undercarriage can then be secured to the end bars 55 as by welding to the clamps 57, if desired, or preferably it can be supplied with its own clamps for removably securing the same to the end bars of the bed frame. It is contemplated that the central bar 69 for the undercarriage be made to telescope in length so as to accommodate varied lengths of conventional bed frames. The telescoping construction for the central bar 69 if provided is preferably located beyond the track means of the undercarriage. The entire under carriage can be manufactured and supplied as a completely assembled and secured unit, or it can be shipped and supplied in knockdown form.

The operation of the form of auxiliary means shown in Figs. 6-11 basically is the same as that of the previously described embodiment although it differs somewhat in the manner in which it is retracted into and extended from its concealed position beneath the main frame. The construction of the pivot connection for the inner tubular member of the rolling carrier will now be described.

The support for the inner tubular member 83 on the track means comprises a pair of eye-bolts 84, each of which is rotatably secured at opposite ends of the rear tubular member. The eye of each eye-bolt is secured about one of the rods 77 of the track means and the stud of the eye-bolt is disposed in the hollow of one of the ends of the rear tubular member 83, the end of the stud being flanged so that the eye-bolt is secure from dislodgment axially of the rear tubular member by cooperation with suitable means such as a cap as at 86 which is welded or otherwise secured to close off the hollow end of each of the rear tubular members and which has an aperture through which the stud of the eye-bolt extends. The pair of eye-bolts is thus freely rotatable about the ends of the inner tubular member 83 and serve the combined function of acting as pivot connections for the rear tubular member and as a means for retaining the rolling carrier afiixed to the stationary structure of the undercarriage. The pivot connection provided by the pair of eye-bolts functions in concert with the pivot-supports, the latter defining the pivot axis for the rear tubular member 83 and providing the greater measure of support for the rolling carrier in all the vertical positions thereof, while the former by its construction permits the rolling carrier to be so pivoted.

Fig. 7 shows the rolling carrier in its supported concealed position within the framework of the undercarriage beneath the bed frame. This is the position of the rolling carrier when the bed is to be used for sleeping purposes and it is retracted into this position by raising the forward tubular member 81 of the rolling carrier slightly and holding the free end of the rolling carrier off the floor while sliding the same over the track means until the forward tubular member 81 has passed by the pivot supports. During the latter part of this movement, the rolling carrier is yieldably urged by the resilient means toward the front side of the bed frame and slight force is required to overcome this urging of the resilient means. The rolling carrier is then engaged in its supported position by simply lifting it slightly and allowing the resilient means to urge the forward tubular member 81 against the pivot-supports. The rolling carrier thus engaged is yieldably biased against the pivot-supports by the resilient means and thereby retained against accidental extension of the rolling carrier laterally from the bed frame. To move the rolling carrier to the operative position as shown in outline in Fig. 8, slight force is applied against the forward tubular member 81 toward the rear side of the bed frame against the urging of the resilient means to disengage the same from and to clear the pivot-supports, following which the free end of the rolling carrier may be lowered to its intermediate drop position as shown in Fig. 8. In this intermediate drop position, the free 'end only of the rolling carrier is floor supported. The rolling carrier may then be laterally extended from the front side of the bed frame by the application of a combined slight lift-and pull motion to the forward tubular member where- 'upon the rear tubular member will engage the pivot-supports secured to the front bar of'the bed frame and prevent further lateral extension of the rolling carrier. The extended rolling carrier can then be pivoted about the pivot-supports to its operative position perpendicular to the bed frame, the rear tubular member being retained within the bed frame by its connection with the transverse tubular members as described. The rolling carrier is retained in its operative position by the cooperating straps adjacent the ends of the bed frame With the aid of the springs and mattress, the straps being drawn taut over the latter and fastened together whereby a unitary assembly is provided which may then be tilted to a sidewise position and conveniently and safely wheeled from place to place.

It will thus be seen that there has been provided by this invention auxiliary means adapted for attachment to a conventional bed frame and a bed construction in which the various objects hereinabove set forth, together with many thoroughly practical advantages are successfully achieved. The combination of bed construction and auxiliary means preferably is constructed with a rigid H main frame which unlike heretofore known roll-away beds is incapable of collapsing and which will accommodate conventional twin, three-quarter or full size springs and mattresses, whereby the comfort of the conventional bed is in no wise diminished in providing the advantages of convenient portability. Many hotels, apartments and motels have a substantial investment in conventional springs and mattresses as these are preferred, and the rollaway bed construction shown and described will accommodate such springs and mattresses wherein lies a substantial advantage over heretofore known types of roll-away beds which cannot use box springs, for example, and which require that the mattress be of a special type which folds within the bed frame.
